To @ZZ whom t may concern:

Beit known that we, WALLACE I. STIMP- soN and EDWARD S. STIMPsoN, ofHopedale, in the county of lorcester and Gommonwealth of Massachusetts,have invented an Improvement in Loom-Temples, of which the followingdescription, in connection with the accompanying drawings, is aspeciiication, like letters on the drawings representing like parts. Y

In the use of temple-rolls with different kinds of cloth much difficultyhas been eX- perienced in the marks which are left by the teeth of therolls on thin iine goods, and with heavy closely-woven cloth the rollsfail to take proper hold, particularly at the selvages, which lattercurl up, and cloth with straight selvages cannot be made.

This invention has for its object the production of a temple-roll whichwill overcome the before-named objections, the wear on the journals ofthe temple-roll being also decreased by our invention.

Figure l is a vertical longitudinal sectional view of a temple-rollembodying our invention, the pod and cap being shown in section. Fig. 2is a side elevation of the temple-roll to more clearly show thearrangement of the teeth. Fig. 3 is a transverse section taken on theline o; er, Fig. l, looking to the right. Fig. 4 is an enlarged innerside perspective view of the dust-protector for the roll-journal, andFig. 5 is a rear-end elevation of the pod and cap with a portion of thesupporting-shan-k.

Referring to Figs. 1 and 5, the inner end of the pod a, forming a partof the shank a', is transversely slotted at a2 to receive a locking-earb formed on the cap b, the latter in this instance supporting thetemple-roll. A lug h2 on the cap (see Fig. 5) rests on the enlarged enda3 of the shank when the cap is in operative position, a bolt bx passingthrough the lug and into a threaded hole in the end a3 retaining the caprigidly in place. The inner end of the cap is downturned at d4, andthreaded to receive and support one of the pivots or stud-bearings c ofthe templeroll CZ, a similar pivot or bearing c being held in the outerend of the cap, as clearly shown` in Fig. l.

We have herein shown the temple-roll as provided with bushings d10,axially bored at the ends to receive and freely turn upon the smoothinner ends of the studbearings c c', the end of one bushing projectingbeyond the end of the roll, as at dx.

It is found in practice that lint, dust, dto., are apt to collect aboutthe inner end bearing of the usual temple-roll, and we have obviatedthis by extending the bushing, as at dx, and insertin g it loosely inthe counterbore e of a protector e. (Shown separatelyin Fig. 4.) Thisprotector is preferably made of brass or other suitable metal, withlaterally-extended wings e?, which enter between the edges of the capand pod, holding it in place, the bearing or pivot c passing through ahole e3 in the protector, the latter also taking up the end-thrust ofthe temple-roll when in use. By this means the necessary longitudinalplay of the roll is permitted while eifectually protecting the bearingfrom the entrance of lint or dirt.

In weaving heavy closely-woven cloth it is found that if the teeth ofthe roll are reduced in number at the outer end of the roll, as at d',Fig. 2, they take a much better hold of the cloth along the selvage, andslack selvages can then be held properly, thus preventing the curling upof the selvage.

lith the usual temple roll, having the teeth disposed equally from endto end, the teeth cannot properly enter and take hold of slack selvages,and cloth with straight selvages cannot be woven. We also prefer to makethe teeth at the outer or selvage end of the roll of uniform height, theteeth gradually decreasing in height from about the point d2, Figs. 1and 2, to the inner end of the roll. This prevents the teeth at theinner end of the roll from taking the greatest hold of the cloth andmarking it, for the gradually-decreasing height of the teeth toward theinner end of the roll causes them to take a gradually-diminishing holdon the cloth inward from the selvage.

When weaving thin fine goods, the arrangement of the teeth as to numberis reversedthat is to say, the teeth are set closer together at theselvage end, so that a greater number engage the cloth at any one time,and being set closer together they cannot enter so decpl y IOO into thematerial, thus avoiding marking. Furthermore, the fclose setting :oftheiteeth enables them to let go of the fabric more easily as the clothis moved along.

The arrangement of the teeth as to height is, however, the same asheretofore,-the teeth decreasing in height from the vicinity of"themiddle of the roll to the'inner'end, as de- V'surface of .theroll,the2teeth -graduallydecreasing in height therefroin'towa-rdftheIend. of fthe roll, the number vfof teeth beingin- 'creasedtoward one:end of the roll, substanrti'ally as described.
